System Information
Operating system: Windows 10 Home, Version 1903
Graphics card: GeForce GTX with Max-Q design

Blender Version
Broken: 2.90.1
Worked: 2.80

Error description:
When using realtive file paths on a fluid or gas simulation, the cache encounters a file write error. This works with any fluid cache type. The realtive path is set to a folder in the same directory as the project.

Error code:

SyntaxError: invalid syntax
  File "<string>", line 1
    liquid_save_data_4('D:\\WorkFolder\\(Hello's)\\cache_fluid_4b85f272\\data', 1, '.vdb', False)

Exact steps for others to reproduce the error
Make a new file and save the file in a folder anywhere with the folder name containing parentheses, or quotation marks. (example: "(Hello's)") Make a sphere, then apply a quick fluid simulation to the sphere. When you move the timeline to make the cache files, or bake the fluid simulation, the program encounters the described error and can't access the files.
Edit: The cache has to be saved in the same place as where the blender file is saved for the error to occur

D8773: Fix #79941: Mantaflow cache doesn't work with ' character in path Seems to have fixed this when I test with 2.91 e12767a035.
I have no issues using (Hello's) as the name of a folder in the file path.
Windows won't let me us " in a folder name as it says it is illegal.
Please try testing with the latest daily build from the following link:

Using provided version (2.91), the problem with having a single quote character in the filepath is fixed
